IMPROVEMENT IN MACHINES FOR ROLLING BLANKS FOR SOCKETS FOR OIL-WELL RODS.

Specification forming part of Letters Patent No. 183,739, dated October 24, 1876; application filed September 20, 1876.

To all whom it may concern:

Beit known that I, LEVI YAKEL, of Allegheny, Pennsylvania, have invented certain new and useful Improvements in Rolls for Manufacturing Blanks for Sockets for Oil- Well Rods and other analogous articles, of

' scribed and claimed.

To enable others skilled in the art to make and use my invention, I will proceed to describe the exact manner in which I have carried it out.

In the drawings, A A represent standards or frame-work, which furnishes bearings for the rollers B G. ()n the roller B is formed the elongated tapering die F, and on the roller 0 is a groove or matrix, G, of corresponding shape, the groove, however, extending entirely around the roller 0, and, where not touched by the die, shaped as shown at H h,

.to make the part which forms the shank of the socket, as shown at k in Fig. 2. The

roller B is provided with the flanges I I, to embrace the ends of the roller 0, as shown in Fig. 1, the flanges fitting in the depressions J J, thus securing a steady movementof the die and matrix as the blanks pass between the rollers. The rollers are provided with the ordinary cog-gearing, and may be operated by means of' the crank E, or by the application of steam or other power. After the blank L has been properly formed, by passing it between the rollers B (3, as above described, it is severed at the point K, and the two parts brought together and welded or otherwise secured, as shown in Fig. 3, the socket-point M being then ready for the reception of the rod. Over the shank N of the socket is passed and secured the ring or collar P, to form a shoulder and give greater security to the socket. Fig. 5 shows a blank partially rolled, the parts 8 8 showing the portions of the blank acted on by the dies, and the portion R representing the portion which is to be formed into the part N, as seen in Fig. 3.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

In combination with a suitable frame, the roller B, provided with the tapering die F, and the roller 0, provided with the matrix Gr and connecting groove H h, substantially as
